One is on the crank shaft pully (for TDC). It is a line, scribed on the pully, that alligns to a pointer on the plastic timing belt cover. The second is on the cam shaft pully. It can be accessed by removing the rubber inspection plug on the timing belt cover. The third is on the auxillary shaft (oil pump) and is also accessed through an inspection plug on the timing belt cover.

On the cam and oil pump pullies, the diamond aligns to the diamond and the triangle aligns to the triangle (the pullies have both). These should be perfectly aligned when the crankshaft pully line is at 0 deg TDC. If you can't see the marks through the inspection port while the crank is at 0 TDC, you are 180 degrees out - turn the crank one more time.

The timing marks are on your timing belt cover. There is a little circle on the bottom right of the cover near the harmonic balancer that you can pop out to see if your distributor accesory gear is in the correct position. The camshaft has a triangle on the inside of the gear that you can line up with this accesory gear. The bottom of the timing belt cover has your timing tick marks and you may have to clean off this rectangular piece that is sticking out on the cover to see the marks. A good timing gun and remembering where the number 1 cylinder on your distributor is a good start to timing your motor. Refer to a Haynes Manual and it will give you a good guide line on how to time your motor with TDC. I hope you have good luck with this!

Rotate the engine so that No. 1 cylinder is at TDC on the
compression stroke. Check that the timing marks are aligned on the
camshaft and crankshaft pulleys. An access plug is provided in the cam
belt cover so that the camshaft timing can be checked without removal
of the cover or any other parts. Set the crankshaft to TDC by aligning
the timing mark on the crank pulley with the TDC mark on the belt
cover. Look through the access hole in the belt cover to make sure that
the timing mark on the cam drive sprocket is lined up with the pointer
on the inner belt cover.

Loosen the alternator retaining bolts and remove the drive belt from the pulleys. Remove the water pump pulley.

Loosen and position the power steering pump mounting bracket and position it aside.

Remove the four timing belt outer cover retaining bolts and remove the cover. Remove the crankshaft pulley and belt guide.

Loosen the belt tensioner pulley assembly, then position a
camshaft belt adjuster tool (T74P-6254-A or equivalent) on the tension
spring rollpin and retract the belt tensioner away from the timing
belt. Tighten the adjustment bolt to lock the tensioner in the
retracted position.

Remove the timing belt.

To install:

Install the new belt over the crankshaft sprocket and then
counterclockwise over the auxiliary and camshaft sprockets, making sure
the lugs on the belt properly engage the sprocket teeth on the pulleys.
Be careful not to rotate the pulleys when installing the belt.

Release the timing belt tensioner pulley, allowing the tensioner
to take up the belt slack. If the spring does not have enough tension
to move the roller against the belt (belt hangs loose), it might be
necessary to manually push the roller against the belt and tighten the
bolt.

The spring cannot be used to set belt tension; a wrench must be used on the tensioner assembly.

Rotate the crankshaft two complete turns by hand (in the normal
direction of rotation) to remove the slack from the belt, then tighten
the tensioner adjustment and pivot bolts to specifications. Refer to
the necessary illustrations. Make sure the belt is seated properly on
the pulleys and that the timing marks are still in alignment when No. 1
cylinder is again at TDC/compression.

you need to pull the timing back apart pull the number one spark plug and role the motor over by hand to top dead center on the compression stroke the the mark for the crank should be lined up or almost lined up line it up perfect on its mark then set the cam to its mark install belt role over by hand 2to4 full rotation marks should line up perfect . install crank pulley fire it up for a split second shut it off and put it all back together
